Anyone tried this?:
http://www.coyotegulch.com/products/acovea/

"ACOVEA (Analysis of Compiler Options via Evolutionary Algorithm) implements a 
genetic algorithm to find the "best" options for compiling programs with the 
GNU Compiler Collection (GCC) C and C++ compilers. "Best", in this context, 
is defined as those options that produce the fastest executable program from 
a given source code. Acovea is a C++ framework that can be extended to test 
other programming languages and non-GCC compilers."

I wonder if there is a "Best" for size rather than speed in ACOVEA?
